Vito Acconci’s design and architecture come from another direction: a background first in writing and then in art. By the late ’80s his work had crossed over, and he formed Acconci Studio, whose operations come from computer thinking and mathematical and biological models. They treat architecture as an occasion for activity and make spaces fluid, changeable, and portable. They are currently working on a three-story building in Milan, a bridge-system and park near Delft, and an amphitheater in Stavanger, and have other projects in Toronto and Indianapolis.
